power calculation when performing ECP.
SRK/T formula performed well in both groups, with no statistically significant difference in the MPE and the percentage of eyes achieving postoperative SE of ±0.50. We consider it is unnecessary to perform any kind of correction to the IOL power calculation when performing ECP.First degree relatives (FDRs) of glaucoma patients are more likely to present for screening when they are directly contacted and educated by health workers on the phone compared with when they are only invited by their relative with glaucoma.
The aim was to determine the effect of direct health education by phone calls on the uptake of glaucoma screening among FDRs of primary open angle glaucoma patients as a glaucoma blindness control strategy in an asymptomatic high-risk African population.
This was a randomized clinical trial in which 102 primary open angle glaucoma patients (probands) were randomized into control and intervention groups. Both proband groups were educated about glaucoma and requested by the investigator to invite their adult FDR to attend a screening clinic within 1 month. In addition, the FDRs in the intervention group were directly contacted, educated, and invited for examination by phone calls. A total of 560 FDRs were enumerated by the probands. The main outcome measure was propoWe recommend direct contact and education of the FDRs of glaucoma patients.
Direct contact and health education of FDRs through phone calls had a significant positive effect on the uptake of glaucoma screening by FDRs. We recommend direct contact and education of the FDRs of glaucoma patients.To compare the efficacy and safety of micropulse transscleral cyclophotocoagulation applied at the level of the pars plicata transscleral micropulse cyclophotocoagulation (PLI-MPC) versus the pars plana transscleral micropulse cyclophotocoagulation (PLA-MPC).
This prospective interventional case series included 44 eyes of 31 medically treated primary open-angle glaucoma patients scheduled for micropulse transscleral cyclophotocoagulation to achieve further intraocular pressure (IOP) reduction. In total, 22 eyes underwent PLI-MPC and PLA-MPC each. Primary endpoints were the reduction of 24-hour mean diurnal IOP (mean of 6 measurements), diurnal IOP fluctuations, and peak IOP, after 3 and 12 months. Secondary outcomes were postoperative complications, a possible deterioration in visual acuity and field, factors influencing IOP reduction, and the number of dropouts.
In the PLI-MPC group, IOP was reduced from 15.9±3.4?mm?Hg to 13.6±3.1?mm?Hg (n=16; P&lt;0.001) and 12.9±3.7?mm?Hg (n=13; P&lt;0.001) at 3 and glaucoma who did not reach target pressure despite maximally tolerated IOP-lowering medication. Although the IOP-lowering effect was not statistically significantly different between groups the pars plicata application was superior and easier to perform and should be recommended as the preferred method of application.Designing and demonstrating an experiment that shows the risk of airborne transmission of COVID-19 between patients having visual fields analyzed is low.
The aim was to investigate the possibility of airborne transmission of COVID-19 during Humphrey visual field testing in a real-world scenario.
A particle counter was placed within the bowl of Humphrey visual field analyzer (HFA) before and after turning on the machine to ascertain the effect of the air current produced by the ventilation system on aerosols. A second experiment was run where the particle counter was placed in the bowl and recorded particulates, in the air, as a 24-2 SITA standard was performed by a mock patient and then again immediately after the patient had moved away. We measured aerosol particle counts sized ?0.3?μm, &gt;0.3?0.5?μm, &gt;0.5?1?μm, &gt;1?2.5?μm, &gt;2.5?5?μm, and &gt;5?10?μm.
Particulates of all sizes were shown to be significantly reduced within the bowl after turning the machine on, demonstrating that the air current produced by the HFA pushes air out of the bowl and it cannot stagnate. There was no significant difference in measurement of aerosol while there was a patient performing the test and immediately after they had moved away, suggesting that aerosols breathed out by the patient are not able to remain in suspension in the bowl because of the ventilation current.
There is no significant difference between aerosol count in the bowl of a HFA before, during and after testing. This suggests the risk of airborne transmission of COVID-19 is low between subsequent patients. This is in keeping with manufacturer's guidance on Humphrey visual field testing.

A total of 200 eyes of 75 patients with POAG and 125 healthy controls underwent corneal topography and densitometry (Oculus Pentacam HR). The data compared in the 2 groups were anterior chamber angle, anterior chamber depth, and anterior chamber volume, keratometry (Kminimum, Kmaximum, and Kmean), central corneal thickness, central anterior elevation, anterior elevation apex, maximum anterior elevation, and posterior elevation apex. Densitometry measurements were made at 3 depths on a 12-mm-diameter circle divided into 4 concentric rings (0 to 2, 2 to 6, 6 to 10, and 10 to 12?mm). https://www.selleckchem.com/products/GDC-0941.html The diagnostic capacity of the corneal variables was assessed through the areas under the receiver operating characteristics curve.
The corneal density of practically all depth layers and total corneal density were significantly higher in the POAG than the control group (P&lt;0.05). Total corneal density was positively correlated with age (r=0.623; P&lt;0.001) and also showed a good diagnostic capacity for glaucoma [area under the curve=0.617; 95% confidence interval (CI) 0.541-0.697; P&lt;0.001]. In a multiple linear regression designed to assess its relationship with age, sex, central corneal thickness, and Kmean, age emerged as a significant confounder both in controls (coefficient=0.315; P&lt;0.001; 95% CI 0.246-0.384) and patients (coefficient=0.370; P&lt;0.001; 95% CI 0.255-0.486).
Corneal densitometry measurements showed a good diagnostic capacity for POAG suggesting this type of examination could have clinical applications in the diagnosis and management of glaucoma.
